1. Listview - Adding an item
Hi all,
I'm currently trying to add an item to a listview i made using a
resource dialog, i think i did it the way it should be done, but it's
not working :(
This is what i got:
function makeLV_ITEM(sequence items)
atom hwnd
hwnd = allocate(36)
for I = 0 to length(items)-1 do
poke4(hwnd+(I*4),items[I])
end for
return hwnd
end function
--- This is inside the WM_INITDIALOG event
LPTSTR = allocate_string("Test")
LV_ITEM = makeLV_ITEM({
or_all({LVIF_TEXT,LVIF_PARAM}),
0,
0,
0,
0,
LPTSTR,
7,
0,
0
})
void = c_func(xSendMessage, {GetDlgItem(hWnd, PANEL1),
LVM_INSERTITEM, 0, LV_ITEM})
free(LV_ITEM)
free(LPTSTR)
--- End
Can any win32 guru tell me where the problem is?
TIA,
Guillermo Bonvehi

I do not think I can help you. I have never worked with true dialogs. Does
GetDlgItem() return the hWnd of the ListView? I also notice that the text
length is givenas 7 but the text is only 4 bytes.

I don't think I could help either but, if you look at my EFFM project
on the RDS site you may be able to get some clues.

4. Re: Listview - Adding an item
Hi again,
Thanks for answering. Actually, i discovered the item is being=20
added, but not with the text i gave it, it's just adding an empty item.=20
I'll keep trying.
Best Regards,
Guillermo Bonveh=ED
PS: Derek, 7 remained there because i changed the word i used for=20
testing before sending the example.
